Tiffen 95mm Coarse Thread Hot Mirror IRND 0.3 Filter (1-Stop)

The Tiffen 95mm Coarse Thread Hot Mirror IRND 0.3 Filter is a combination of both a hot mirror infrared (IR) control filter and a 0.3 neutral density (ND) filter. A hot mirror IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard ND filter to counter the increased light sensitivity afforded by the HD sensor, the effects of IR pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of IR light reaching the sensor while still maintaining the extra exposure benefits of an ND filter. The hot mirror filtration incorporates a dielectric mirror in order to combat the effects of both near and far IR regions of the spectrum.
